Engine noise when driving on high speed

Hello all, my car's engine seems to be normal. It does not make noise etc on low speed or idle. But when I accelerate and drive it on high speed. Then its engine noise loud. I checked other Civic's of the same model. But they were not creating that much noise. What could be issue?

Also recently, I washed the car at service station. After that, I noticed when I turn the steering wheel either to right or left. It also creates sound.

Please help.

Thanks
